Mega Man X — Linux (AppImage, initial/experimental)

Initial experimental Linux release — x86_64 AppImage.

Bring your own ROM. Place your legally-dumped Mega Man X (.sfc) ROM in the same folder as the AppImage; it's auto-detected at launch. No ROM is included.

Run it

chmod +x MegaManX-x86_64.AppImage
./MegaManX-x86_64.AppImage          # add --appimage-extract-and-run if FUSE is unavailable

Steam Deck / controllers — the AppImage reads the controller natively. In Desktop mode, launch through Gaming Mode (or set a Gamepad controller layout) so face buttons aren't remapped to keyboard keys.

Production build — no debug server / tooling. Early, experimental Linux port; expect rough edges. Source: this repo.
